System Dynamic Simulation Study On The Coordinated Development Of Environment-Economic In Undeveloped Area

Environment-economic system is a complicated system which has different characteristics in different area. After the west exploit been put forward, more and more areas have done the study of sustainable development. Facing with some undeveloped areas' problems that lagged developing social and economic, how to advance economic and protect environment in west have been the main content of sustainable development study and have most important meaning for the balance of our country, economic boom and stability social.Taking the district of Youxin village Chengdu Sichuan province as an example, this thesis discuses the coordinated development of environment-economic system by system dynamic. On the bases of knowing characters of environment-economic system in Youxin, we divided the system to three parts: environment, economic and population put the part of environment to the emphasis and found out the influences between each part. Based on those studies, we established the SD model of Youxin village with which we have simulated some policy projects.Traditional agriculture was the main economic pattern in Youxin that had little large-scale and industrialization agriculture and less industry and service. The atmosphere and surface water quality in Youxin is up to the mustard of our country's corresponding standard, and there were little environment pollution. Through the un-changed policy simulation, we learnt that the developing economic would lead to more environment pollution if we wouldn't adjust the policy and insist it. The...
